Effect of random telegraph noise on entanglement and nonlocality of a qubit-qutrit system

We study the evolution of entanglement and nonlocality of a non-interacting qubit-qutrit system under the effect of random telegraph noise (rtn) in independent and common environments in markovian and non-markovian regimes. we investigate the dynamics of qubit-qutrit system for different initial states. these systems could be existed in far astronomical objects. a monotone decay of the nonlocality (entanglement) is found in the markov regime, while for non-markovian noise, phenomena of sudden change (death) and revival occurs. we find that the preserving nonlocality (entanglement) depends on initial state of the system in common and independent environments; so, we can not strictly conclude that independent or common environments are more robust against the noise.
